NASCAR legend Greg Biffle was thrilled to be back in the sky just months before his airplane crashed and killed himself, his wife and two kids. "Excited to get back flying again," Biffle, 55, shared via Instagram in September. Biffle showed off a picture from inside his Cessna 550 Citation II, the same plane that crashed at Statesville Regional Airport on Thursday, December 18. The crash killed Biffle, his wife, Cristina, his 14-year-old daughter, Emma, and his 5-year-old son, Ryder. Four other individuals were also killed in the crash.
